Microsoft is currently refusing to confirm Harrison's departure to various publications, with a representative telling IGN that "Microsoft does not comment on rumors or speculation." Xbox head Phil Spencer told Eurogamer at GDC, "I don't, no. I'm sorry, I don't think I can say anything about that" when approached about the matter. Chris Charla, director of ID@Xbox, also couldn't comment on the reports.

The departure marks a three year tenure with Microsoft when Harrison joined the corporation as VP of the Interactive Entertainment Business and EMEA head of games in March 2012. He was previously head of Sony's global network of studios before resigning from the electronics giant in 2008. In the interim, he was a partner in an investment capital firm he founded called London Venture Partners and was also previously on the board of Atari.
